If you have difficulty creating a database, check the following:
Ensure you have started the management agents on all the hosts and defined an HADB domain. For details, see Starting the Management Agent
File and directory permissions must be set to allow read, write, and execute access to the install, history, device, and config paths for the following users:
Sun Java System Application Server administrative user (set during installation)

For details about setting user permissions, see Preparing for HADB Setup
Sun Java SystemMessage Queue: 7676

HADB nodes: Each node uses six consecutive ports. For example, for default port 15200, node 0 uses 15200 through 15205 , node 1 uses 15220 through 15225, and so on.
Disk space must be adequate; see the Sun Java System Application Server Release Notes.
